Previously our sig limit was 550x250 pixels but sometimes we allowed people to go a bit over but some people seem to think this means they can go 800 pixels over the limit, and this is not the case.
So we have decided to increase the limit to 600 pixels wide by 300 pixels high and we will not tolerate anyone being over the limit, even if its just a few pixels over the limit. This rule will be in effect immediately because it is an increase in the limit and if anyone is already breaking this rule they were definately breaking the old limit.
The reason we have a signature limit is because people get annoyed when they have to scroll down a full page to go past peoples signatures and they clog the forums with crap.
Added the picture jeff made so people see it right away
Umm..the image link is broken so I edited in the one from the rules. ~Bib
